摘要：
A ghost cancellation method for the multi-touch sensitive device is disclosed. The multi-touch sensitive device includes a sensing array having multiple lines of a first axis and multiple lines of a second axis intersecting with each other. All the lines of the sensing array are scanned to determine which ones of the lines are touched, so as to determine touch point candidates. For each touch point candidate, a driving signal is applied to the line of the first axis, and the line of the second axis is detected to check if the touch point candidate is actually touched.
